It's got Corrosion Taped

The selection of anti‐corrosive protective materials for metal pipelines is generally based upon a consideration of three basic factors. Briefly, we can list them as follows: the atmospheric conditions or, in the case of an underground or underwater structure, the soil or water conditions that will be encountered by the line; the ease and economy with which the protection can be applied; and lastly the durability of the material in the face of not only corrosive shock but mechanical stresses. The problem is complicated by the fact that few such pipelines meet with uniform conditions throughout their length.
